Abstract: In an embodiment, a method for interactively varying scheduling of a multi-threaded application executing on a symmetric multi-core processor provides an interface in a co-simulation design environment. The interface is associated with a multi-threaded application executing on a target processor that includes symmetric processor cores. The method also sets a scheduling attribute of the multi-threaded application using the interface. The setting occurs when the multi-threaded application is executing. The method further receives data associated with the executing of the multi-threaded application in the co-simulation design environment when the multi-threaded application is executing subsequent to the setting of the scheduling attribute.

Abstract: In one embodiment, a method of implementing interrupt prioritization and preemption in a modeling environment is provided. The method may include obtaining a model including interrupt-generating components in the modeling environment, obtaining information describing interrupts in the model, and using the information describing the interrupts in the model to automatically generate code for prioritizing the interrupts in the modeling environment.

Abstract: A device generates code with a technical computing environment (TCE) based on a model and information associated with a target processor, registers an algorithm with the TCE, automatically sets optimization parameters applied during generation of the code based on the algorithm, executes the generated code, receives feedback based on execution of the generated code, and uses the feedback to automatically update the optimization parameters and to automatically regenerate the code with the TCE until an optimal code is achieved for the target processor.

Abstract: A device may connect to a physical device. A device may obtain a device description document relating to the physical device based on connecting to the physical device. The device may parse the device description document to identify one or more components of the physical device. The device may select, from a repository of generic textual model components, one or more generic textual model components corresponding to the physical device based on parsing the device description. The device may generate, based on selecting the one or more generic textual model components, a device driver model element that includes the one or more generic textual model components. The device driver model element may be used to control the physical device or receive information from the physical device. The device may provide, via a user interface, information identifying the device driver model element.

Abstract: A method may include receiving, by a device, information associated with a model. The method may include determining, by the device, performance criteria for program code generated based on the model. The method may include determining, by the device, profiling information associated with the program code. The method may include determining, by the device and based on the profiling information, that the performance criteria is not satisfied. The method may include applying, by the device and based on determining that the performance criteria is not satisfied, a modification technique to a portion of the model to create a modified model. The modification technique may be applied to the portion of the model to cause program code, generated based on the modified model, to satisfy the performance criteria.
